Jay asked:


What type of device will allow you to put electrical energy from the electrical source to a battery? Let’s take an example that you are probably familar with-the fur and rod example. If I rub the two together I get an electrical charge. Now, what would I attach to the rod and fur and what device would be able to put that electrical energy into a battery?
Example 2-How do you store the energy that is being made from a mechanical device? If you know of specific products please list them.
